 The installer detects your OS and architecture automatically. On macOS it supports both Intel and Apple Silicon. On Linux it supports x64 and arm64. The launcher is installed to `~/.local/bin`, the bundled runtime is unpacked into `~/.local/share/feynman`, and your `PATH` is updated when needed.
 
-If you previously installed Feynman via `npm`, `pnpm`, or `bun` and still see local Node.js errors after a curl install, your shell is probably still resolving the older global binary first. Run `which -a feynman`, then `hash -r`, or launch the standalone shim directly with `~/.local/bin/feynman`.

-## pnpm

-If you already have Node.js `20.19.0` or newer installed, you can install Feynman globally via `pnpm`:
-
-```bash
-pnpm add -g @companion-ai/feynman
-```
-
-Or run it directly without installing:
-
-```bash
-pnpm dlx @companion-ai/feynman
-```
-
-## bun
-
-`bun add -g` and `bunx` still use your local Node runtime for Feynman itself, so the same Node.js `20.19.0+` requirement applies.
-
-```bash
-bun add -g @companion-ai/feynman
-```
-
-Or run it directly without installing:
-
-```bash
-bunx @companion-ai/feynman

-
-Both package-manager distributions ship the same core application but depend on Node.js being present on your system. The standalone installer is preferred because it bundles its own Node runtime and works without a separate Node installation.

 ## Post-install setup
 
 After installation, run the guided setup wizard to configure your model provider and API keys:
